bad sensor
to look at the gauges something is terribly wrong!!
Check the radiator/condensor fan for proper operation.Check the radiator/condensor fan for proper operation.
You probably have an open or short in the electrical system. It should be fine for now but you might want to get it checked out, it will eventually just fail.
It could be sprained. You should get it checked out without delay at your local Accident and Emergency department to get it xrayed for proper diagnosis.
It depends on what is wrong with it. It probably has a freon leak. Add some freon, and listen for a leak. Always charge the system through the low side of the system. If you don't hear a leak, then add the required capacity, and the unit will last through the summer, if there is not a component failure. The best way to check the system is with air conditioner pressure gauges.
have you checked the battery output? it should show right at 13.4 volts, if not, check your alternator output.
You start by figuring out what's wrong with them, then proceed from there.
One of the gauges is telling you something is wrong. It could be it's overheating or not charging or no oil pressure.
have the freon charge checked if the freon is low the evap core can freeze and the air flow is restricted and no air flow or little air flow is the result
Only after you have put a set of gauges on the a/c system to read both the high and low side pressure readings then you can determine if you need to add freon and oil to the system. If you just add freon and oil because the a/c system is not as cold as it once was it could still be full but might have something else wrong with it. The one thing that you don't want to do is buy one of the do it yourself kits and overcharge the system, this could lead to an expensive repair due to overcharging the a/c system..........
Mine is out of Freon.
Your speedometer may have failed, or the speedometer cable that connects to the transmission, or the plastic gear in the transmission may be broken.
